These counterparts from RS PRO are for use with electro-holding magnets. They're basically steel armature plates for the electromagnets to clamp onto. Because of the size of the fixing holes, they're suitable for both energise-to-hold and energise-to-release electromagnets.

A nickel plating on the steel increases the magnetism of these plates for an even stronger hold. Nickel is an extremely corrosion resistant and hardwearing material.

This counterpart weighs just 50 g and is 40 mm in diameter, so it's both compact and lightweight. This model is for use with 30/35 mm sized electro-holding magnets.

An RS PRO quality product, this armature plate has been thoroughly tested by engineers for safety and reliability. It meets standards ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007 for safe levels of electrostatic discharge during handling and packaging.

Counterparts such as this one are typically used in magnetic locking systems, such as applications for security gates and doors.
